This patch adds reptyr, a tool for reparenting a running program to a
new terminal. I put it in screen.scm because it is usually used to move
a process into a screen or tmux session.

Also somewhat related, I think the file tmux.scm should merge with
screen.scm.

Thanks,

Thank you, I will use this :)

If we are considering moving these packages around, I think that
screen.scm and tmux.scm should go into terminals.scm. But, I also think
that this patch should not be held up by that discussion.

Why skip the tests? We prefer to run tests whenever possible. Otherwise,
please add a comment explaining why. For example "No test suite."

This is short and sweet, but we like to use modify-phases for
consistency.

We should capitalize the beginning of the description, and I would also
wrap 'ssh' and 'screen' in texinfo:

@code{ssh}
@code{screen}
